ORGANIC LIGHT EMITTING DEVICE PERFORMING ALL SOLUTION PROCESSES CAPABLE OF IMPLEMENTING AN ELECTRODE AS SOLUTIONS

摘要

PURPOSE: An organic light emitting device performing all solution processes is provided to obtain sufficient luminous efficiency without an energy loss between layers by applying a self-assembled monolayer between a cathode and an electron transport layer as a surface reforming layer.;CONSTITUTION: An anode (120) is formed on a substrate (110). A hole transport layer (130) is formed on the anode. A light emitting layer (140) is formed on the hole transport layer. An electron transport layer (150) including ZnO nanoparticles is formed on the light emitting layer. A surface reforming layer (160) is formed on the electron transport layer to form a self-assembled monolayer. A cathode (170) is formed on the surface reforming layer.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Substrate; (120) Anode; (130) Hole transport layer; (140) Light emitting layer; (150) Electron transport layer; (160) Surface reforming layer; (170) Cathode
